Our research interests and current focuses are:

1. Regulation of neurotransmitter receptor function
We are interested in the dynamic regulations of excitatory and inhibitory neurotransmitter receptors in the brain. We have found several key endosomal trafficking molecules that are essential for the expressions of AMPA and GABAA receptors on the membrane surface or at synapses, and demonstrated that dysregulated receptor trafficking influences synaptic transmission, synaptic plasticity and cognition in mice. We are studying how excitatory/inhibitory balance is regulated to maintain proper neuronal function and animal behavior.

2. Regulation of synapse development and maintenance
Synaptic connectivity is dynamic and determined by a balance among synapse formation, elimination and maintenance that continues throughout development into adulthood. In the visual and mouse hippocampal circuits, we have identified signaling pathways that are essential for specific regulations of synapse formation during development and synapse maintenance in adult age. Utilizing time-lapse imaging in culture neurons and two-photon imaging in living mice, we aim to gain insights into how neuronal activity and sensory/learning experience shape neuronal circuits in vivo and in real time.

3. Glutamatergic synapse function in neurodevelopmental disorders
Human genetic studies suggest that glutamatergic synapse structure and function are common underlying pathophysiology in developmental brain diseases. We have investigated several disease-associated genes and provided functional links between miss-regulated glutamate receptor function and neurocognitive disorders, including intellectual disability and autism spectrum disorder. We are investigating the underlying etiology in our disease mouse models with the ultimate goal to facilitate the development of therapeutic treatments for these disorders.
